Stochastic phase separation driven by transport noise
Andrea Di Primio, Andrea Papini, Luca Scarpa
Phase separation phenomena occurring in complex fluids are known to be sensitive to hydrodynamic effects: when a binary fluid mixture undergoes spinodal decomposition, the emerging…
Approximation of the Lévy-driven stochastic heat equation on the sphere
Annika Lang, Andrea Papini, Verena Schwarz
The stochastic heat equation on the sphere driven by an additive square-integra\-ble Lévy process is approximated by a spectral method in space and forward and backward Euler--Maru…
Average dissipation for stochastic transport equations with Lévy noise
Franco Flandoli, Andrea Papini, Marco Rehmeier
We show that, in one spatial and arbitrary jump dimension, the averaged solution of a Marcustype SPDE with pure jump Lévy transport noise satisfies a dissipative deterministic equa…
Effect of Transport Noise on Kelvin-Helmholtz instability
Franco Flandoli, Silvia Morlacchi, Andrea Papini
The effect of transport noise on a 2D fluid may depend on the space-scale of the noise. We investigate numerically the dissipation properties of very small-scale transport noise. A…
Increasing biases can be more efficient than increasing weights
Carlo Metta, Marco Fantozzi, Andrea Papini +7
We introduce a novel computational unit for neural networks that features multiple biases, challenging the traditional perceptron structure. This unit emphasizes the importance of…
Smoluchowski coagulation equation with velocity dependence
Franco Flandoli, Ruojun Huang, Andrea Papini
In the present article we introduce a variant of Smoluchowski's coagulation equation with both position and velocity variables taking a kinetic viewpoint arising as the scaling lim…
Turbulence enhancement of coagulation: the role of eddy diffusion in velocity
Franco Flandoli, Ruojun Huang, Andrea Papini
A Smoluchowski type model of coagulation in a turbulent fluid is given, first expressed by means of a stochastic model, then in a suitable scaling limit as a deterministic model wi…
Coagulation dynamics under random field: turbulence effects on rain
Andrea Papini
Turbulence in growth of rain droplets and rain formation is studied under an approximating particle system representing aggregation at the level of individuals, depending on their…
Epidemic Models as Scaling Limits of Individual Dynamics
Franco Flandoli, Francesco Grotto, Andrea Papini +1
Infection spread among individuals is modelled with a continuous time Markov chain, in which subject interactions depend on their distance in space. The well known SIR model and no…
